You guys are confusing me.

Anyways. I've just plopped in another stack of floppies and neither worked. The disk would be read for 3 seconds upon which the aforementioned message would pop up.

Another thing I've just realized: whenever I remove a disk, the heads will make a short screeching sound and seem to slightly lower themselves.


Sounds like the head guides and stepper-motor worm-drive just need re-greasing - hardly surprising for a 15 year old drive that's never been used.

Sounds plausible.
Thanks.

Are there any publicly available instructions I could download? I'm not very hardware savy (at least when it comes to non-synthetic/non-theoretic stuff).


Yep:

  • drive to electronics store, buy non-conductive electronics grade grease and isopropyl alcohol
  • open case, remove fdd, remove fdd cover (if it has one), use isopropyl alcohol on lint free cloth to clean the long worm-drive gear etc and the 2 guides that the head mechanism slides up and down on (look for evidence of dry or old grease to know where to clean).
  • apply grease to dry part of lint free cloth and thouroly cover areas just cleaned with fine coating of grease.
  • plug drive back in with cover still off and use a head-cleaning disk on drive about a dozen times till you can see head mechanism moving smoothly and quietly.


that should do it and the heads will get a good clean too. :)
